Having trouble with making a wifi extender

I have been trying to use relayd to make a wifi extender and the tutorial is fine, its just that when i reboot after installing luci-proto-relay the interface does not come back up. the tutorial I am using is. https://openwrt.org/docs/guide-user/network/wifi/relay_configuration

Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button (red circle; this works best in the 'Markdown' composer view in the blue oval):

Remember to redact passwords, VPN keys, MAC addresses and any public IP addresses you may have:

ubus call system board
cat /etc/config/network
cat /etc/config/wireless
cat /etc/config/dhcp
cat /etc/config/firewall

Assuming, you have suitable hardware, a faster (and more modern) alternative is to use WDS for the repeater. https://openwrt.org/docs/guide-user/network/wifi/wifiextenders/wds Simple, MT76x8 based deice will suffice. Better, when having 2 radios, of course.

my device is a netgear nighthawk r7800. It does have 2 radios

I have trouble with ssh in, I have to reboot my computer when ever I do the step that changes the routers ipv4 address.

I would have to factory reset the wroter to be able to ssh in again.

that's kind of expected though, isn't it ?
not the reboot, but the lack of access, unless you change your client's IP to the same subnet.

I my sorry I don't know what you are talking about but I could understand why i need to reset it sorta. I was able to get as far as instaling luci-proto-relayd. again but I can't get back to the web ui post reboot. I cant even ping it.

and we don't know what you've done, welcome to the club.

did you

  • Finally, set your PC's Ethernet port to use a static IP in the Wi-Fi extender subnet (e.g., 192.168.2.10) and default gateway (e.g., 192.168.2.1), then use Ethernet to connect again to the extender.

I set it to a static ip and pinged it again.

.2.67 is the client ?

don't post screen shots, they're not searchable.

https://openwrt.org/docs/guide-user/network/wifi/relay_configuration#install_relayd_package is where you're stuck ?

there's one quirk, the wwan IP, if it's already assigned to a diff device on your LAN, you won't be able to tell which device you're talking to.
make sure the IP you assign is outside the upstream DHCP's range.

Are you able to show your configurations as requested?

We can't guess from the model and brief descriptions.

Then, you really need to understand that concept.

i set it to .2 as doesn't it have to be on the same subnet, yes i am stuck there, I do not know my dhcp range, also it is very late where I am so I will be going to bed after I post this.

what's upsteam of the 7800 ?

a asus RT-AC1900P runing stock firmware

I was able to get it working, what worked was resetting my dns everytime I rebooted it and switching from a computer running windows to one runing linux.
